FB.login not returning auth response after login with two factor authentication
We have implemented Facebook login on our React application. Our "Log in with Facebook" button's click handler calls FB.login. We have supplied a callback to FB.login that handles the response and authenticates with our backend using the provided access token.
The works in most cases - except if the user has two-factor authentication enabled on their Facebook account. In this scenario, if the user successfully goes through the flow in the Facebook popup to complete two factor authentication and verify their identity, the popup closes - but the response object supplied to the FB.login callback has a status of "unknown" and does not include an access token.
The user must then click "Log in with Facebook" a second time, and only then is a successful auth response supplied to the FB.login callback.
Looking for support in handling this scenario so that the user does not need to click "Log in with Facebook" twice in order to authenticate with our app.
Facing a similar issue on my facebook app for users with 2FA enabled.
Facing the same issue here too. The sdk only updates the log in status when a user gets to the 2FA page with an "unknown" status and there won't be any other auth response objects after that point. In order to log in successfully, the user has to start the log in again in which case an auth response with "connected" status is received.
Same issue.
